This card promises blistering speeds and robust durability, claims I’ve been eager to test in real-world scenarios.

The advertised shockproof, temperature-proof, and waterproof nature adds a layer of reassurance for those who use their cards in demanding environments.

Performance

In my testing, the SanDisk Extreme microSDXC card consistently met, and sometimes exceeded, its advertised read and write speeds. Transferring large 4K video files was notably faster than with my previous card. The A2 rating also proved beneficial when using apps on my Android phone. App load times were noticeably quicker, a significant improvement in usability. I experienced no lag during continuous 4K video recording, a testament to its write speed capabilities. I even subjected the card to some light (and accidental) drops and rough handling—it held up surprisingly well.

However, I did notice some minor inconsistencies in write speeds under extremely high-load conditions, like simultaneously recording 4K video and capturing photos. The performance dip wasn’t dramatic, but it was noticeable. This is a minor issue, especially considering the overall performance.

Pros & Cons

  • Pros: Fast read and write speeds, reliable performance, durable build, A2 rating for improved app performance.
  • Cons: Minor write speed inconsistencies under extremely high-load scenarios, slightly higher price point compared to some competitors.

Final Verdict

The SanDisk Extreme microSDXC Card (SDSQXAH-064G-GN6MN) is a high-performing card that delivers on its promises of speed and durability. While minor inconsistencies in write speed exist under heavy load, they are negligible for most users. The speed improvements, especially in 4K video recording and app performance, are substantial. For the price, it offers excellent value and provides peace of mind with its robust construction. I would confidently recommend this card to anyone needing a reliable and fast microSDXC card for their devices.
